The office of Bishop was ordained by God"For the nurturing and constant growth of the People of God, Christ the Lord instituted in His Church a variety of ministries, which work for the good of the whole body. For those ministers, who are endowed with sacred power, serve their brethren, so that all who are of the People of God, and therefore enjoy a true Christian dignity, working toward a common goal freely and in an orderly way, may arrive at salvation. This Sacred Council, following closely in the footsteps of the First Vatican Council, with that Council teaches and declares that Jesus Christ, the eternal Shepherd, established His holy Church, having sent forth the apostles as He Himself had been sent by the Father; and He willed that their successors, namely the bishops, should be shepherds in His Church even to the consummation of the world." (Lumen Gentium 18)

"Christ, whom the Father has sanctified and sent into the world, has through His apostles, made their successors, the bishops, partakers of His consecration and His mission. They have legitimately handed on to different individuals in the Church various degrees of participation in this ministry. Thus the divinely established ecclesiastical ministry is exercised on different levels by those who from antiquity have been called bishops, priests and deacons." (Lumen Gentium 28)

"Since the apostolic office of bishops was instituted by Christ the Lord and pursues a spiritual and supernatural purpose, this sacred ecumenical synod declares that the right of nominating and appointing bishops belongs properly, peculiarly, and per se exclusively to the competent ecclesiastical authority." (Christus Dominus 20)

The office of Priest was ordained by God"Thus the divinely established ecclesiastical ministry is exercised on different levels by those who from antiquity have been called bishops, priests and deacons." (Lumen Gentium 28)

"The same Lord, however, has established ministers among his faithful to unite them together in one body in which, 'not all the members have the same function'. ... Christ, through the apostles themselves, made their successors, the bishops, sharers in his consecration and mission. The office of their ministry has been handed down, in a lesser degree indeed, to the priests. Established in the order of the priesthood they can be co-workers of the episcopal order for the proper fulfillment of the apostolic mission entrusted to priests by Christ." (Presbyterorum Ordinis 2)

"God, who alone is holy and who alone bestows holiness, willed to take as his companions and helpers men who would humbly dedicate themselves to the work of sanctification. Hence, through the ministry of the bishop, God consecrates priests, that being made sharers by special title in the priesthood of Christ, they might act as his ministers in performing sacred functions." (Presbyterorum Ordinis 5)

The office of Deacon was ordained by God"For the nurturing and constant growth of the People of God, Christ the Lord instituted in His Church a variety of ministries, which work for the good of the whole body. For those ministers, who are endowed with sacred power, serve their brethren, so that all who are of the People of God, and therefore enjoy a true Christian dignity, working toward a common goal freely and in an orderly way, may arrive at salvation." (Lumen Gentium 18)

"Thus the divinely established ecclesiastical ministry is exercised on different levels by those who from antiquity have been called bishops, priests and deacons." (Lumen Gentium 28)

Men are called to the Priesthood by God"The effective union of the whole people of God in fostering vocations is the proper response to the action of Divine Providence which confers the fitting gifts on those men divinely chosen to participate in the hierarchical priesthood of Christ and helps them by His grace." (Optatam Totius 2)
